AI faces important adjustments, and scientific foundations are confronted with new breakthroughs, as AI enters a new stage： AI 2.0. This paper briefly reviews the 60-year developmental history of AI, analyzes the external environment promoting the formation of AI 2.0 along with changes in goals, and describes both the beginning of the technology and the core idea behind AI 2.0 development. Furthermore, based on combined social demands and the information environment that exists in relation to Chinese development, suggestions on the develoDment of Al 2.0 are given.展开更多

The purpose of this community research was to trace the spread and impact of sweetpotato flour in two rural communities in Papua New Guinea. Research strategy was participatory learning and action utilizing participatory mapping. The paper mapping process was documented using a video recorder and field notes. Geographic Information Systems technology was then used to incorporate local spatial knowledge on scale maps to show spread of knowledge. The main finding was the identification of social networks through tracking of sweetpotato knowledge： identifying who used the knowledge and whether there were any modifications, the location of those who used the knowledge and whether this was shared and with whom. Most significant was the enabling factors that strengthened existing and potential future networks. Community leadership styles determine success of development projects. Rural communities are diverse needing participatory multi-layered methodologies that are people oriented for agricultural technologies to be learnt and utilized for improved livelihood.展开更多

Nowadays, as a matter of fact, Information and Communications Technologies （ICTs） continue excluding part of the population and contribute to a top-down organisation of the main streams of information neutralising active potentialities and risking, paradoxically, to isolate users who are not aware of the mechanisms of the lnternet. The ＂doxic＂ acceptance of web contents, structures, and tools indeed precludes some kinds of knowledge and some different models of participation, with significant consequences on the social construction of reality. As a result, a tendency emerges towards a virtual-only participation and the click-tivism seems more and more to be turning into a form of slack-tivism.展开更多

Political participation has to be affected by the social and economic development, political system, social and environmental factors, countries generally believe that collaboration between the Government and social organizations, networks of enterprises, schools and other interested parties are currently the main mode of network governance. College students are the main power of the network of political participation, the university plays an important role in the political participation process. Therefore, this article takes online political participation of college students as a starting point, through questionnaires and case interviews and other methods to investigate the current status of college students online political participation, analyze network characteristics and problems of college students in political participation, to guide the college network path which provides reference for orderly participation in political studies.展开更多
